چکیده

The present study was conducted on Hubbard classic broiler parents in the Bangladesh Rural Advancement Committee (BRAC) poultry farm in Chittagong, Bangladesh to know the productive, reproductive performance and for modelling the performances for their prediction. The average live weight and egg production of Hubbard classic broiler parent were obtained as 3412.48 ± 137.773 g/hen and 170.99 ± 1.012 eggs/hen/year, respectively. By using the parameters of linear regression and quadratic polynomial regression equation the yearly predicted egg production (number), live weight (g) and feed intake (g) were predicted. The R and CV fit statistics were used to compare the model performance and actual and predicted values. The actual and predicted value for live weight and feed intake was similar except yearly egg production (number).
